Brief Summary

The goal of this prospective observational study is to assess the post-operative pain in adults with digital amputation following two different surgical interventions: microanastomosis of digital nerves or traction neurectomy. The main questions it aims to answer are:

• Which surgical intervention results in less post-operative pain?
• Which surgical intervention leads to fewer symptoms after six months?
• Which surgical intervention is associated with fewest post-operative complications? Participants will complete a Visual Analog Scale (VAS) to assess the pain and the Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH) to evaluate the disabilities. The researchers will assess post-operative complications during follow-up appointments.

Outcome Measures

Primary Outcomes (2)

• Postoperative Pain Measured by Visual Analog Scale in Adult Patients Following Digital Amputation

  The primary objective of this study is to compare the level of postoperative pain associated with two surgical techniques: microanastomosis of digital nerves and traction neurectomy. Pain will be measured using the visual analog scale at one week, four weeks, and six months following the procedure. The visual analog scale ranges from 0 ( no pain) to 10 (worst imaginable pain).

  1 week, 4 weeks and 6 months

• Postoperative Symptoms Measured by the Disabilities of the Arm, Shoulder and Hand Questionnaire in Adult Patients Following Digital Amputation

  The secondary objective of this study is to compare the level of postoperative symptoms associated with two surgical techniques: microanastomosis of digital nerves and traction neurectomy. The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire will assess disability and hand-related symptoms at 6 months. The score ranges from 0 (no disability) to 100 (most severe disability)

  6 months

Secondary Outcomes (1)

• Complication Rate of Microanastomosis of Digital Nerves and Traction Neurectomy in Adult Patients Following Digital Amputation

  1 week, 4 weeks, 6 months

Study Population

Individuals presenting at the Centre Hospitalier de l'Université de Montréal for a digital amputation

You may qualify if:

• Age ≥ 18 years
• Patients who have undergone a traumatic digital amputation
• Patients treated with one of the two following techniques: microanastomosis of digital nerves or traction neurectomy
